It happened in 2012, it happened last year, and it is happening again this year.

Following rumors suggesting the iPhone 6 would launch in July and then August, a new report from German Apple blog iFun suggests that the launch will take place in September. The report cites unnamed sources in claiming that Apple Stores in Germany will restrict employee vacation time in September in order to ensure that all hands are on deck for the iPhone 6 launch.

Apple restricts vacation time ahead of and during its iPhone launches each year, though it typically doesn’t begin informing employees of this restriction until much closer to the iPhone’s release date.

While reports attempting to pinpoint the next iPhone’s release time frame have been all over the map during the past few months, the smart money has remained on a September release. Extremely reliable Apple analyst Ming-Chi Kuo reported back in early April that Apple’s iPhone 6 would debut late in the third quarter.

According to Kuo, the iPhone 6 will feature a brand new design with a 4.7-inch, 1,334 x 750-pixel display, as well as a new Apple A8 processor and NFC. The analyst also says that a second new iPhone model with similar specs and a 5.5-inch full HD screen will launch sometime later in the fourth quarter.
